SignalsLib

SignalsLib is a small library plugin for writing event-driven Minecraft plugins with a simple signal API backed by GEB. It comes in one jar per platform:

Platform	Jar
Bukkit, Spigot, Paper	SignalsLib-Bukkit-*.jar
Folia	SignalsLib-Folia-*.jar
BungeeCord, Waterfall	SignalsLib-BungeeCord-*.jar
Velocity	SignalsLib-Velocity-*.jar

Usage

Install the jar for your platform in the server or proxy plugins/ folder (only one of the Bukkit and Folia jars, they share the plugin name SignalsLib), then add this to your plugin:

depend: [SignalsLib]

BukkitSignals.shared()
    .players().join()
    .connect(event -> event.getPlayer().sendMessage("Hello!"));

Fluent event options are available:

BukkitSignals.shared()
    .players().interact()
    .high()
    .ignoreCancelled()
    .connect(event -> event.getPlayer().sendMessage("Interacted"));
